Elevator could also make a decent guess at fullness just by recording the discrete changes in weight. It wouldn't be perfect but again it would probably be better than allowing user input.


i believe all elevators at least have a failsafe to refuse to run if they are overloaded. going from there to tracking and using the actual weight for its programming is not a big step


Oh, elevators know to some accuracy how many people-mass things are in it. It just rarely has reason to use that information.
